Disney-Style Rendering, Eevee or Cycles?
I would suggest Cycles since PRMan is actually quite accurate in light calculate and the latest version also contain the ray tracing option/ability to render the scene. 



Despite EEVEE is aiming for accurate light result, but it is still a little bit far away from the word accurate. It could speed up the scene setting and light setting, but you will need to switch to Cycles for a better result.

And Disney style use a lot of graphic effect and trick to mock the fluffy touch of the scene and also making the scene match the real world scene. Beside that, the final clip we saw has been post-processed in movie editor like Premiere or whatever they use. Making it more difficult to achieve the same image effect in Blender only.

So you might try using Cycles + Photoshop to tweak the style, not EEVEE unless you are familiar to deal with all the lighting problem that EEVEE might meet. And you can also use both EEVEE and Cycles to do different part of the scene rendering and merge them in post-processing stage.
